Abstract: In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

Abstract: When a gradation mask is used to distribute image data to be recorded by overlapping portions in an overlapping head, color unevenness is generated in an image recorded by the overlapping portions due to a displacement in impact positions caused by an assembly error. As a result, accurate colorimetric measurement of patches recorded by the overlapping portion cannot be performed. To solve such a problem, a distribution ratio by which the image data is distributed to the overlapping portions is set to be approximately constant when recording a test pattern for performing color correction, as compared to when normally recording the image.

Abstract: In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

Abstract: In image processing, it is possible to suitably reduce density unevenness and graininess according to the ink used in printing. More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.

Abstract: When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.

Abstract: In image processing it is possible to adequately reduce density unevenness and graininess according to the duty of the image data. More specifically, when dividing multi-valued data and generating 2-pass multi-pass printing data, in addition to the divided multi-valued data for each of the two passes, divided multi-valued data that is common to both of the two passes is also generated. Moreover, the quantized data of that common multi-valued data is reflected on the quantized data of each pass. Furthermore, when generating quantized data, the division ratio when generating common data in the division of multi-valued data is set according to the duty (gradation value) of the multi-valued data. By doing so it becomes possible to adequately reduce the density unevenness and graininess according to the duty of the image data.

Abstract: When the number (M) of passes is smaller than a threshold value, a first processing mode is selected. In the first processing mode, multivalued image data is divided into pieces of multivalued data corresponding to passes and a common multivalued data for a plurality of passes, the pieces of multivalued data are individually binarized to generate pieces of binary data corresponding to the passes, and the common multivalued data is binarized to generate common binary data for these passes. On the other hand, when the number (M) of passes is equal to or larger than the threshold value, a second processing mode is selected. In the second processing mode, multivalued image data is binarized and the binary data is divided into pieces of binary data corresponding to passes with a mask.

Abstract: Provided are an image processor and an image processing method that are capable of suppressing both density unevenness due to printing position shifts among a group of dots printed by a plurality of relative movements (or a plurality of printing element groups) and graininess. In order to accomplish this, a dot overlap rate in the printing mode in which the density unevenness stands out is made higher than the dot overlap rate in the printing mode in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to the image characteristic, and output an image having no density unevenness or graininess.

Abstract: Multi-valued image data corresponding to a pixel area is divided into the first scanning multi-valued data, first and second scanning common multi-valued data, and second scanning multi-valued data. A quantization processing is executed on each of the multi-valued data to generate first scanning quantized data, first and second scanning common quantized data, and second scanning quantized data. After that, these pieces of quantized data are combined for each scanning to generate first scanning combined quantized data and second scanning combined quantized data. According to this, the amount of pixels where dots are both recorded by performing a scanning by plural times (the amount of overlapping dots) is controlled, and while suppressing the image density variations, the granularity is held to a low level.

Abstract: Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

Abstract: Inputted image data is converted to M number of multi-value data having a lower resolution than the inputted image data, and after quantization processing has been performed for each of the M number of multi-value data, an image is printed by M number of relative movements (M-pass printing) that corresponds to the M number of quantized data. By doing so, when compared with the case in which a resolution reduction process is not performed, it is possible to suppress the number of pixels that become the object of quantization processing, and it becomes possible to output an image with no fluctuation in image density or density unevenness without a decrease in the processing speed.

Abstract: The present invention suppresses data processing load and processing time when generating density data for the same color that corresponds to a plurality of printing scans (or plurality of printing element groups) of a printing head and printing medium. In order to accomplish this, input image data is converted to a plurality of density data by referencing a three-dimensional lookup table that performs one-to-one correlation of input image data with a plurality of density data that corresponds to a plurality of relative movements (or plurality of printing element groups). By doing so, it is possible to perform a process of generating density data (CMYK) that corresponds to a plurality of relative movements (or plurality of printing element groups) from input image data at once, and thus it is possible to suppress an increase in data processing load and processing time.

This makes it possible to output a high-quality image having excellent robustness and reduced graininess by controlling the overlap rate of dots that are printed by the first relative movement and the dots that are printed by the second relative movement.

Abstract: When recording is performed in a pixel region by M (M is an integer equal to or larger than 2) passes with N (N is an integer equal to or larger than 2) recording element groups, density variation due to a deviation between recording positions of dots that are recorded by different passes is suppressed while a load of data processing is decreased. First, multivalued image data (24-1 to 24-2) corresponding to the M passes is generated from input image data, and the multivalued image data corresponding to the M passes is quantized to generate quantized data (26-1 to 26-2) corresponding to the M passes. Then, the quantized data corresponding to the M passes is divided into quantized data being complements of each other and corresponding to the N recording element groups. Accordingly, the quantized data (28-1 to 28-4) corresponding to the M passes for the N recording element groups is obtained.
